Abstract

Three experiments were conducted to compare Cu and Zn sources. Experiment 1 evaluated the effects of various Cu and Zn sources and levels on ruminal in vitro dry matter disappearance (IVDMD) of starch and cellulose substrates, and Experiments 2 and 3 used stressed (marketing and transport) heifers to study the effects of Cu and Zn source on performance, morbidity, and immune response.
